Data storage is a common term for archiving data or information in a storage medium for use by a computer.

Memory is very much like our brain as it is used to store data and instructions. Computer memory is the storage space where data is to be processed, and instructions needed for processing are stored. The memory is divided into a large number of smaller portions called the cell. What is Primary Memory? Primary memory is the main memory of the computer system. Accessing data from primary memory is faster because it is an internal memory of the computer. The primary memory is most volatile which means data in primary memory does not exist if it is not saved when a power failure occurs.
Difference Between Primary and Secondary Memory
Computer storage devices are typically classified into primary storage or main memory on the one hand, and secondary storage or peripheral storage on the other. Primary memory also includes registers, cache, and video memories, but we will ignore them for this discussion because their existence does not affect the principal differences between primary and secondary memory. Along with a faster CPU, every new model of computer seems to come with more main memory. As memory size continues to increase, is it possible that relatively slow disk storage will be unnecessary? Probably not, because the desire to store and process larger files grows at least as fast as main memory size.

By the end of this chapter, you will be able to:. In this section, you will get more detail about the purpose of storage, what the difference is between primary and secondary storage, why computers need storage and what online storage is. You will be introduced to the storage devices that do the processing in a computer, such as the motherboard, random-access memory RAM , read-only memory ROM and central processing unit CPU and what their functions are.
Data storage is one of several basic, yet vital functions a computer performs. The concept of storage itself is defined by a hierarchy of four levels: primary storage, secondary storage, tertiary storage, and offline. This post will serve as a primer for those who need an introduction or refresher course. Typically located inside the computer, primary storage temporarily houses applications and data currently in use.
The memory of a computer is classified in the two categories primary and secondary memory.
Difference between Primary and Secondary Memory
Computer data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. The central processing unit CPU of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy ,  : — which puts fast but expensive and small storage options close to the CPU and slower but less expensive and larger options further away. Generally the fast volatile technologies which lose data when off power are referred to as "memory", while slower persistent technologies are referred to as "storage". Even the first computer designs, Charles Babbage 's Analytical Engine and Percy Ludgate 's Analytical Machine, clearly distinguished between processing and memory Babbage stored numbers as rotations of gears, while Ludgate stored numbers as displacements of rods in shuttles.
Computers use main memory such as random access memory RAM and cache to hold data that is being processed. However, this type of memory is volatile - it loses its contents when the computer is switched off. General purpose computers , such as personal computers and tablets, need to be able to store programs and data for later use. Secondary storage is non-volatile , long-term storage. Without secondary storage all programs and data would be lost the moment the computer is switched off.

Difference between Primary and Secondary Storage
Difference between Primary storage and secondary storage Primary memory is the main memory Hard disk, RAM where the operating system resides. Secondary memory can be external devices like CD, floppy magnetic discs etc. Difference between Primary storage and secondary storage - Primary memory storages are temporary; where as the secondary storage is permanent.
